Falling Debris Trap CR 1
Type mechanical; Perception DC 10; Disable Device DC 15
Trigger touch; Reset none
Effect Atk +5 melee (1d6, debris); multiple targets (drops 1d4 pieces of debris on each target in the room) net strung up near the ceiling holds a number of stones and a small metal anvil, rigged to fall on anyone walking through the door without noticing the trip rope (the door opens out). Each character entering the room must make a DC 10 Reflex save or set off the trap. Those who make it do not necessarily notice the trap.
If set off this trap not only harms intruders, but the noise also warns anyone nearby of their presence.
